I'm somewhat of a perfectionist so I did plenty of research when it was time to retire my old road-weary amp. Roland has made a very versatile product with the KC series. I've used it for small and large gigs. And when you need that extra output for large gigs, this amp delivers! I've had this amp since 1999 and have no intention of retiring it or replacing it.

I bought the KC 350 for gigging and was impressed by how close the amp came to the true patch sounds. I am also using the 350 as an acoustic guitar amp and find that the quality of my two Taylor acoustics comes through beautifully. The power of 120 Watts enables me to do large venues, outside concerts, and small venues without necessarily having to run the keys through a PA system. Worth the money!!

I bought two because I wanted the stereo sound. Really don't use them for anything else. No technical hook-ups. But I really like the sound. Get a lot of compliments on it. Plenty of volume with no distortion. The only complaint I have right now is that Roland evidently does not have amp covers, so I'm going to have to have some made.

I bought one to my church because are small and has a super stereo sound. Plenty of volume with no distortion. Its easy to carrier.

The mixing and stereo-link features are terrific, but the quality of the sound is not that great, the tweeters are constantly blowing out (and I don't play in loud bands), and the knobs fall off all the time. Considering the price, I would expect better reliability. If you can find one, buy a groove-tube "spacestation" stereo amp. It's smaller and sounds way better. And if you need mixing capabilities, add a small mixer.
